- in schools. t It is hollow and sectional aiid provided with means tor securing the sections detachably together and to the axis upon which the globe revolves in a suitable frame.-

Inl connection with the globe proper I einploy a curved and graduated ruler adapted to :nc-ve or swing around the globe and for use in indicatingr and drawing nieridians and `parallels on the surface.

The details of construction and arrangement 'and combination ofparts are as hereinafter described, and illustrated in the accompaiiying drawings, 11i which,

iguie 1 is a sectional view of the globe and a side view of the frame in which it is supported and adapted to rotate. Fig. 2 is a detail section of the polar section of the globe. Fig. 3 is a perspective view of the lower portion of the graduated ruler. Fig. 4 is a transverse central section of the globe or a plan view of the lower hemisphere, the graduated ruler being in sectionl Fig. 5 is a side view ofthe globe together with the graduatedlrulciz Fig. 6 is a detail section showing the notched disk or wheel with pawl which is applied to the lower end of the axis of the globe for holding it -fixed in any adj ust nient.

The hollow globe A is supported in a frame consisting of a horizontal base portion B and a curved vertical bar B. The body of the be formed of hemispheiical sections or a great number of scctions. Thus, in this instance each hemisphere is divided into four sections all of like dimensions. The meeting ends of the several sections aie secured together at the poles bj. Ymeans which will be presently described.

he `globe revolves upon an axis C, arranged at the usual angle of twenty-three degrees, having pointed eiids,one of which is stepped in the frame at c and the other enters a conv ical depression in the end of the clampingscrew D which is arranged in the upper end of arc bar B. On the lower end of the axis C is secured a toothed or ratchet wheel -h see Figs. 1 and 6; Aspring pawl or dog e is pivoted adjacently and its free end engages l the disk E. In practice itis preferred that the disk E shall have thirt v-six notches so that when the globe is rotated and stopped and held by means of'the pawl, the distance moved will be one degree-on the surface of the globe. The axis C alined sleeves and similarly constructed and arranged mainly projecting slightly from the polar ends of the same. A nut f--see Fig. .--is applied 'to each sleeve F on the inside of the globe, and

passes through thev F which are of equal lengthwithin the globe, their outer ends such nut abuts a plate G which is concavo convex in forni. A similar plate G"'is"ap plied on the outer side of the globe. A lint j" is applied to each sleeve F exteriorly to the plate G and a jam nut f is screwed on the axis C and abuts the adjacent l end of the sleeve, and also the nutf.

It will now be understood that the polar corners of the sections constituting each of the heinispheres of the globe lie and are clamped between the concavo-convex plates G, G, and that they may be readily detached by screwing the nut back on the sleeve and axis. ing side edoes of the several heinispherieal sections in c ue. j uxta osition with each other I prefer to employ c owel pins H-see Fi. 5-the same being held in one section and the projecting pin adapted to enter the socket in the adlacent one as will be readily understood.

By the above described construct-ion of the globe it is apparent that it is adapted to be In order to hold the nieetmade very large or of great diameter, say five feet or more, and that the two hemispheres or the several sections of the hemisphere ma?r screwed into collars c that are applied to the meeting ends of the alined sleeves F, while their outer ends are similarly engagedwith clips or brackets `i which are rivetedor bolted I which are arrange( radiall as indiz o cated 1n Figs. i and 4, their inner ends being l. to the circumferential hoops J, -as shown in Each hoop J extends around the inner side of the glo Figs. 1 and 4.

e adjacent to the diameter of the same, the tivo hoops thus r lying juxtaposed. The end s of the rods J are screw threaded in o osite directions to adapt them to be readi y inserted and' removed from their connections.

The curved ruler li having central lateral extension K', both portions being graduated in degreesof latitude and longitude, is applied in connection with the globe proper,

)oth parts K, K', being'eurved concentric- 1 all)v with the globe and so attached te the I axis C or rather to the projecting ends of the i sleeves F that it may rotate er swing around the globe and thus be' set in any required position. The ends of the longer ruler K are provided with notches l: adapted to receive the projecting ends of the sleeves for the nut j" applied thereto, and a hook 7c is pivoted adjacently and ada ited to pass around the nut so as to secure t ie ruler lfroin accidental detachment and yet permit it to be deta\ched whenever required. It will be seen that the longer ruler K is serviceable for indicating ineridians oi'i'thc globe surface, While the horizontal one Kfis similarly available for indicating longitude,

Both may also be used by a pu il for draiv@ ing meridians and parallels on a lank globe, an exercise in which pupils may require instruction.

That I claim is:

1. The improved geographical globe constructed hollow and in sections, an axis passing through the saine, sleeves applied to said axis interiorly of t-he globe, concave-convex clamping lates applied interiorly and exteriorly of tie globe, and nuts applied to the said sleeves and the axis for clamping the globe sect-ions and preventing movement on the axis, substantially as described.

2. The improved geographical globe con-i structed hollow and in sections, an axis interiorly of the globe passing through the same, sleeves applied to said axis and also projecting from the polar portions of the globe and provided tliereat with screw threads, and means applied to the outer ends of the sleeves and axis for preventing inove nient of the globe sections outwardly or from each other, substantially as described.

3. The improved geographical globe constructed holloiv and in sections Whose edges meet upon the diameter of the globe, an axis passing through the globe, and radius rods "extending between the axis and the diametrical edges of the globe sections substantially described.

4. The improved geographical globe hav-v ing a holloiv body formed in sections which ineet at the diameter of the globe, an axis extending through the globe, hoops arranged interiorly of the globe sections and juxtaposed at the. diameter of the saine, and radius tie-andbraee rods extending beti'veen the axis and said hoops and detachahiy connected therewith, substaiitiall)v as described.

, 5. The improved geographical globe-constructed hollow and in sections which meet upon the diameter of the globe, and an axis extending through the globe, `circumferential hoops arranged at the diainetrical edges of the sections and juxtaposed as shown,

threaded sockets provided on the axis and Vitnesses:
